If you're looking at the times from the Motorland Aragon circuit and wondering how come they're ten seconds slower than the MotoGP riders, it's because they're riding a different track layout. Where MotoGP runs a single long sweeper as the final corner, the World Superbike series races the configuration which includes the more finicky hairpin at the end of the back straight, which takes the riders back to the start and finish line. That short section adds 270 meters, but the hairpin is where they are losing all the time.
The conditions haven't helped either. While ambient temperatures are merely nicely warm (32°C) the track temperature is absolutely scorching, approaching 60°C under the burning Spanish sun, and with no shade around the circuit, there is little to cool the track.
Despite that, it was Marco Melandri's day. The Yamaha man benefited from having raced here last year with MotoGP, and also from a recent test at the track, but mainly, Melandri is just back in the groove again after Misano. For both sessions, the Italian was comfortably fastest and is looking like getting faster. Melandri is 23 points down on Max Biaggi in the championship, and looking like pushing the Alitalia Aprilia rider for 2nd place, especially with Biaggi struggling on the first day of practice in Aragon.
